Missing OAuth2 option during generator execution

[vcupelloni]

Overview of the issue

In the authentication type section of the generator, the OAuth2 option is not displayed.
If I manually edit the .yo-rc file at the end of the project configuration and re-run the generator, it appears that the code is updated correctly.

Has the option been hidden for a specific reason?

Reproduce the error

Install JHipster and Micronaut blueprint and run the generator.

Anyone knows if is there any particular problem preventing the use of OAuth2 authentication on a microservice as well as on a monolith?
